Hoist Crane Control

Crane hoists are machines that are able to lift and carry heavy objects and move them to another location. Preventive maintenance and monitoring of operating parameters along with protection of crane equipment is highly important. It is essential to protect critical equipment, increase efficiency and crane service life.

Dedicated to simple and standard hoisting machines, this is the first step towards automation from traditional relay architectures. High-level expertise is not required thanks to simple and predefined adjustments which allows for quick setup of the smart relay. At the same time, this architecture provides a highly compact and simple installation, thus reducing commissioning and maintenance times.

The monitoring function is based on a logic controller for acquiring, recording, and providing warnings on relevant and critical issues for preventive maintenance purpose. It provides information on the working safety period of the gear box, improper crane operations, and important occurrences such as overload and over speed. When the nominal speed is exceeded, the controller must trigger an emergency stop and the function sends an alarm to control the situation. This makes installation easy for maintenance while increasing competitiveness.
